Abstract: A terminal device includes an operation section in which an operation instruction is performed by being touched with a finger or a pen; an operation detection section that detects that the finger or the pen touches the operation section; a vibration motor that rotates a shaft with a weight having a center of gravity at a position that is shifted from a rotation center; a vibration state detection section that detects state of vibration caused by rotation of the shaft of the vibration motor; and a control section that starts the rotation of the vibration motor when the operation detection section detects the touching, and stops the rotation of the vibration motor when a phase detected by the vibration state detection section falls within a predetermined range.

Abstract: When communication is performed simultaneously with two moving bodies such as a satellite, an antenna construction in which a plurality of antennas do not become an obstacle to each other's communication and the direction (the azimuth angle and the elevation angle) adjusting mechanism thereof can be realized with a simple construction. The two antennas have another movable portion (a rotation mechanism with respect to the axis) independently, while sharing the direction adjusting mechanism for the azimuth angle and the elevation angle. The rotation axis of the rotation mechanism of each antenna faces the same direction on the same plane, and each rotation mechanism is separately arranged in an area defined by a plane obtained by extending the axis of the azimuth angle adjusting mechanism toward the axial direction of the elevation angle adjusting mechanism.

Abstract: A radio transceiver is provided for wireless communications, having an interface connection that is selectable between either an antenna or a cable interface. The radio transceiver is engaged to the antenna through an impedance matching network which translates the antenna impedance to match that of the radio transceiver. The radio transceiver can, alternately, be connected to external test equipment or performance enhancement equipment through the cable interface. Since the radio transceiver has the same impedance as most external test equipment, the antenna matching network is not required or used when test equipment is connected to the cable interface. In the present invention the cable interface at least partially disconnects the matching network whenever the cable interface is in use. Once the antenna has been disconnected, the impedance of the cable interface matches that of the radio transceiver.
